The Google Vision API is part of the Google Cloud and includes among many interesting services also the option for text detection.

Cloud Vision allows easy integration to vision detection features within applications, including image labeling, face and landmark detection, optical character recognition (OCR), and tagging of explicit content.

Google Vision APIs have emerged to be an immensely helpful tool for OCR and document text detection. It is a cloud OCR service that automatically detects as well as extracts text and data from PDF files and scanned documents. It goes beyond simple OCR to also identify the contents of fields in forms and data stored in tables. 

Google Cloud Vision APIs can seemingly give life to limitless application possibilities, combined with Python libraries. It is fundamentally Google’s pre-trained model that detects faces and objects and performs image recognition, labeling, classification, and text extraction of handwritten or printed text from images and documents.
